FURNACE. I

Application filed. December 5, 1918,.

To ,aZZwhom it may concern:

Be it known that I, THoMAs BINKS KrrsoN, a subject of the King of Great Britain, residing at 72 Albion street, Leeds,

in the county of York, England, have in vented certain new and\ useful Improvements in or Relating to Furnaces, of which the following is a specification.

which the incoming air is heated on top of the furnace by the waste heat and gases.

According to the invention, the heating of the air-supply is effected in a flat chamber orflue between the furnace crown and a top flue for the waste gases. These gases are led-from the furnace direct to the waste flue without passing through any regen: crating-or recuperating device. The said- -heating chamber or flue is free and unob- I while inside it, and thus has time tobecome- 33, of Fig. 1.

structed from end to end, so that it can be j easily cleaned out, and it may be made of such a size that the air'only travels slowly heated properly. g I Thefurnace is also provided Wlth an 1mproved arrangement'to prevent the glass be coming chilled or set accidentally at the discharge holes .or troughs where it is withdrawn from the furnaces.

In the accompanying drawings V Figure 1 is a vertical longitudinalsection of one construction of the improved furnace for use in glass manufacture. a 7

Figs. 2 and .3 are horizontal sections thereof respectively on the lines 2-2, and

Fig. 4: is an elevatlon of the left-hand part or working head of the furnace, viz., the

part where the glass is withdrawn. Fig. 5 is a part transverse section on the line 55 ofFig.

Fig. 6 is a part vertical longitudinal section on the line 6-6 of Fig. 1. r a is the body of the furnace, which is of oblong form, with a low roof or crown 6. Its left-hand end or working head is provided with the waste-gas ports, outlets or uptakes leading to a waste flue d at the top of the furnace, having at their bottom ends troughs d for the out-flow of the glass at the holes I).

At the same end of the furnace, are provided short ports or uptakes e for the airsupply which supports the combustion.

Any suitable known arrangements may be provided for regulating the rate of flow Specification of Letters Patent.

They open into the aforesaid short uptakes e-whichlead to the intermediate heating chamber or p ofthe furnace. The crown of the'furnace a forms thebottom of the intermediate flue h, while the roof or crown of the latter in its turn forms the bottom of the upper or waste-gas flue '03. These crownsor roofs are arch shaped in transversesection as shown in Fig. 5.

V The'heating chamber h is made .much deeperithan the waste 'fiue d, so that it holds a large body of air which therefore flows more slowly through it, and has time to becomeproperly heated. g, I
